摘要： Provided is a liquid crystal display device using a VA-mode liquid crystal with which the viewing angle characteristics are improved in terms of luminance, and the display quality can be improved better than a previous liquid crystal display device. For an operation of multiplex driving with respect to a sub pixel 20A, in a highlight luminance range, a liquid crystal application voltage to be applied to the liquid crystal element 22A is set so as to take a higher-side voltage being equal to or higher than an input application voltage corresponding to a video signal D1, and at the same time, shows a tendency to be lower compared to that in a region with an intermediate level of luminance. This accordingly prevents the variation of azimuth angle of liquid crystal compared with a previous operation of multiplex driving. Further, for an operation of multiplex driving with respect to a sub pixel 20B, in a lowermost luminance range, the liquid crystal application voltage to be applied to a liquid crystal element 22B takes a lower-side voltage being equal to or lower than the input application voltage corresponding to the video signal D1, and at the same time, shows a tendency to be higher compared to that in the intermediate luminance range. This accordingly prevents the occurrence of a phenomenon of rebounding during overdriving compared with the previous operation of multiplex driving.
